– Unpack the files into a directory
– Run BITCOIN.EXE
– It automatically connects to other nodes

If you can keep a node running that accepts incoming connections,
you’ll really be helping the network a lot. Port 8333 on your
firewall needs to be open to receive incoming connections.

The software is still alpha and experimental. There’s no guarantee
the system’s state won’t have to be restarted at some point if it
becomes necessary, although I’ve done everything I can to build in
extensibility and versioning.

You can get coins by getting someone to send you some, or turn on
Options->Generate Coins to run a node and generate blocks. I made
the proof-of-work difficulty ridiculously easy to start with, so
for a little while in the beginning a typical PC will be able to
generate coins in just a few hours. It’ll get a lot harder when
competition makes the automatic adjustment drive up the difficulty.
Generated coins must wait 120 blocks to mature before they can be
spent.

There are two ways to send money. If the recipient is online, you
can enter their IP address and it will connect, get a new public
key and send the transaction with comments. If the recipient is
not online, it is possible to send to their Bitcoin address, which
is a hash of their public key that they give you. They’ll receive
the transaction the next time they connect and get the block it’s
in. This method has the disadvantage that no comment information
is sent, and a bit of privacy may be lost if the address is used
multiple times, but it is a useful alternative if both users can’t
be online at the same time or the recipient can’t receive incoming
connections.

Total circulation will be 21,000,000 coins. It’ll be distributed
to network nodes when they make blocks, with the amount cut in half
every 4 years.

IOTA is a new way, evolution of the blockchain concept to create nets like trees (called Tangle), using the power of the Internet Of Things. Transactions free of taxes. Faster.. but it’s just the beginning

Actually Bitcoin has 2 official forks ( because the fear to “update/evolution” Bitcoin software), Bitcoin Cash (with 8MB blocks instead of 1MB) and Bitcoin Gold (with GPU Mining like Ethereum). The problem of Bitcoin is the transaction cost, because Bitcoin is very expensive. Another problem is that the Bitcoin Core is mining mainly in China (70%) and this is a problem, because Bitcoin isn’t decentralized at this moment and remember the possible attack of the 51%. The nodes must be well recompensed.
